My $0.02 on the subject:
I got married at age 34 and had my son at 47 (we tried for years.. had to go the IVF route due to several issues). Through my 20s I resigned that I would never marry as my experiences were (abbreviated list):
Out of college I was working with older guys who were jealous over the fact I was single. Mind you, I was game-less and rarely dating, so it wasn't my sex life that they were jealous with. Unlike them, I was financially relatively in good shape and could speak my mind freely. The former was in spite of earning a fraction of what these guys were making (the demands of their wives put them deep in debt) and the latter was due to them being married to women with a feminist streak. The married guys overall were all miserable and deep in debt.
I am a nerdy engineer which for younger women puts me well below the 'top 20%' of the male dating pool that women aim for. I also entered the job market during the Clinton "peace dividend" when defense spending cratered and heavy industry got exported overseas. It was a shit job market that didn't pay well. The women who were available were making demands that a 20 something guy make "at least $120k a year" (1990s mind you).
The women friends would hook me up with were financial / emotional disasters. Six figures of student loan and credit card debt and a "walking on eggshells around her" personality. I was on a knife edge financially since every spare nickle I had was going into buying distressed real estate (pre housing bubble days when urban property was dirt cheap) and couldn't risk being attached to a financial boat anchor. This meant I was driving an old car, wearing old clothes, not eating out, and bringing my lunch to work... not exactly emitting an 'aura of wealth'. Plus, try being a right-wing guy around a woman who went through the college feminist NPC factory.. it isn't fun. I am not the person to live my life self censoring and had woman looking at me gape mouth in shock over an opinion I stated.
One job I worked a group from Texas. In that group was one guy who I would describe as happily married. We shared a common interest (international travel) and he gave me the following advice:
"Buy an introductory service (this was 1994, very early world wide web days) like the Cherry Blossoms catalog. Write to a whole bunch of women in countries you plan to visit. In the process of writing, you will figure out which ones you have something in common with. When you arrive in her country, you will have a translator, tour guide, and a "gringo inflation" shield that will stop the locals from tripling prices when they see you are an American." He married one of the women he visited (from Columbia).
I took his advice writing to women all over the world. By 1999, by virtue of putting several $100k through a credit card, I had enough frequent flier miles to go anywhere in the world 1st or business class. My original plan was to head to Chile (skiing). However, Asia was just too damn cheap to ignore (post 1997 Asian financial crisis). So I headed to Thailand. I had one girl who I met via (now defunct) Yahoo Messenger, talking to her twice a day. We met in Bangkok April of 2000. Liked her so much I kept going back to see her. Got married 4 years later in a full Buddhist wedding in Bangkok.
As other posters and the OP pointed out, there are culture clash issues. This wasn't so bad for me because my wife, who is a bit of a black sheep, her whole life wanted to be in the USA. She wanted to become American. So she assimilated quickly. The other positives she brought to the marriage is she had real education (B.S. in economics... no SJW crap), was financially responsible (she already owned a home at age 23), and was trustworthy. The latter is really important as I found so many women in my 20s to be shockingly unreliable in so many aspects.
Having kids late:
If you are a guy who keeps yourself in shape (free weights lifting, watch the carb intake, zinc, and magnesium supplements work well for older guys) then having a kid in your 40s is fine. At this point in my life, I am in a good position to support my kid financially (he will not set foot in the shit public schools here) and frankly, am a lot calmer and wiser than I was when I was say 25. My own parents had kids in their early 20s with no money... it was not a pleasant childhood for my older siblings.
Age is an issue for women. By age 40, the chances of getting a good embryo fall under 5%. As an example: My sister-in-law went into deep "baby mode" after meeting her nephew. She did three rounds of IVF without success. Her eggs were just too old to be viable.
If you want kids, you need a woman under age 35. Ideal "baby making" age range is 17 to 25. Middle and later 30s, you might want to put $$$ for IVF. The 'genetic load' post age 30 goes up and the latest genetic testing can screen out the defective embryos before implantation.
The fact the OP has embraced Christianity might give him a better chance of meeting a quality woman in the right age range. However, I think his best bet will be to go overseas. I did a thought experiment not too long ago: "What would my dating life be like if suddenly I no longer had a wife". Holy shit! What I discovered was not pleasant. The available pool of women was abominable. Granted, I am in an urban area that is deep blue.. but still...
